How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Geometers construct a mobile or ornament using nets of three-dimensional polyhedrons. Not only do they need to compute the volume and surface area of each figure, they also earn points for creativity, neatness, and more!

For this 3D figure worksheet, students observe the net of a 3D figure where you open up the figure and tell if it is an accurate representation of that figure. Students complete this for 3 figures.

Time to find out what they've learned! The final lesson of a five-part series has learners complete a 39-question multiple choice review. They use what they've learned in the previous lessons to complete questions that include concepts...

Boost lemonade sales by using the perfect container. For a given volume, future entrepreneurs design a container that will have the least surface area and by extension, the least cost of material. They create a two-dimensional net of...

In this geometry worksheet, students cut out a net of a cone by following along the dotted lines as indicated by the scissors icon. They fold the figure to form a three-dimensional cone which they tape together. There are no directions...

For this geometry and art worksheet, 3rd graders trace and cut out a cubic net to fold and glue together to learn about the dynamics of three-dimensional figures and shapes.

In this geometry worksheet, students cut out a rectangular prism net. They cut along the dotted lines as indicated the scissors icon, and fold the piece along the solid lines to form the three-dimensional shape. There are no directions...

In this math net worksheet, students cut out, fold, and assemble a closed cylinder. Students use the net provided to make the three dimensional figure.

Identify the nets for prisms and other geometric shapes. Learners calculate the surface area of the rectangular prism then sketch the shapes of prisms and other polygons. Unfolded cereal boxes are used as a visual aid, great idea!

In this math worksheet, students use the math net pattern to construct a model of a rectangular prism. Students cut, fold and tape this 3 dimensional figure.

Partners use materials to wrap three-dimensional objects to determine the formula for surface area. The groups use an orange to calculate the amount of peel it takes to completely cover the fruit. Using manipulatives, individuals then...

For this nets of figures worksheet, students determine which given shapes will make a shown net, then name the shapes uses. A reference web site is given for additional activities.

Sixth graders explore three-dimensional objects. In groups, they create and decorate their own polyhedron design. After identifying the faces, vertices, and edges of the polyhedron, 6th graders determine a relationship between the...

Why are only four colors needed to color webs from regular pentagons, not five? An assessment task requires young mathematicians to first construct regular pentagons using a compass and straightedge, then has them consider a shape...

Hook your charges on how to solve a real-world art problem with mathematics by showing works of Christo. You can find eye-catching images on the Christo and Jeanne Claude webpage. Here, math learners help Jean Claude and Christo prepare...

Students sketch the nets for given polygons and cylinders. For this geometry lesson, students find the measurements that correspond with prisms, cones and cylinders. they identify parts of three-dimensional shapes.

Students sketch the shape of three dimensional pyramids using nets. In this geometry lesson, students differentiate a pyramid from other three dimensional shape. They define the attributes of pyramids.

Pupils compare and contrast two dimensional polygons and three dimentional nets by examining the differences in drawings. They create three dimensional shapes and label the faces, edges, and vertices. After creating the shapes, they draw...

This hands-on lesson takes young geometers on a tour of 2D polygons and 3D polyhedrons. After exploring different web resources and discussing geometric shapes, small groups construct models of polyhedrons using bendable straws. Note:...

Whether you wrap it or fill it, you're using geometric concepts. Classmates use an interactive approach to learn how to find volume and surface area of cylinders and prisms in the second lesson in a five-part series. The online lesson...

When painting a barn you have to calculate surface area, and that is exactly what this resource is about. Not only will your future home owners calculate the surface area, but also the cost. It is a real-life problem that every that...

Finalize the plans before playing in the sand. Learners design sandcastles using geometric and composite figures. They create blueprints, including the scale, and three-dimensional models of their castles. Finally, scholars calculate the...

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...
